/*In C, one function can call another. Write a program that calls a function named one_
three(). This function should display the word one on one line, call a second function
named two(), and then display the word three on one line. The function two() should
display the word two on one line. The main() function should display the phrase
starting now: before calling one_three() and display done! after calling it. Thus, the
output should look like the following:
starting now:
one
two
three
done!   */
